A healthy middle-aged man was treated for isolated scaphotrapeziotrapezoid joint osteoarthritis with implant arthroplasty using a Pyrocardan implant. We report implant breakage twice during tennis training, and the debut of squeaking after the first failure. The implant was revised and replaced both times. Revision of the implant resolved the squeaking. To our knowledge, this is the first report of a type of complication with this implant, indicating potential limitations for its future use.
Sarigiannis et al. (Mon,) studied this question.
